Y In storage batteries of this tvpe 'rnueli di culty is encountered inproviding ineens for holdin the active rneterial'in pro erv Yesition eplete or grid. lfnen t e e eotrode with this applied materiel issubjected to the intiuenoes; of expansion end eontreetion in theeiering, tileinetelliefgrid'or support is to e; strain, sensing werpinU orbue The action of the eleetrolvtie iluid on the active materiel tends todisintegrate it, and unless the grid is so eonstrneted es to securelyretain it in place some oi the entire motorini will seperate from theresin bodv and aoeninnlete et the bottom of the oeil. This will tend toeeuse short-cireuiting and will also serve to still fertlier Werp thegrid. This warping of the grid wili also @ense the dislocation of moreactive rnsterieL the sev cumulation of Winer; et tine bott-oni of thV*li isili the danger from enerve-irn and greetiy shortenthe life of theelio, n; sides destroying trie efficiency of tlie eleotrede.

ln order to obtain the moet desirable resultsefnd etein the greatesteiieienej; forten batterylit is essential that Wiiiie the entirematerial or material to become satire einst be securely retained on thegrid free end open places must be provided through wiiien theelectrolyte may 11nd free eirenietion to attack and set upon the activematerie-l.

My invention has for one obeet the provision of means whereby the activematerial or materiel to become estive shell be firmly secured and heldagainst dislod ent in the electrode under the innenee o the charge anddiseiiarge of the electrornotive force.

A. fnrtller oojeot of my innention is to provide Ineens for thefre'ecirculation and enetrstion of the electrolyte in end eronn the outer andsuojeoent exposed surfaces of the meterisl.

A further object of my invention is the pre- Speecation of Lettersiraient.

'Referring by letter to the aecompsnyin drawings, ,A represents thebedrr of the grdg, Wliiei eonstitutes e support for the estive materielor material to become active. This grid. which is shown as construe-tedwith solid edees B, is made up of a series of longi-` tudinal gersr,which, While they may 'be of any other shape, are here shown asrectangular. @n eiiner ieee of this grid are strips D, which in i ereshown as extending diagonally the fece, with the strips on opposite eeesin staggered relation to eee-li other. In .y ig. 5 l have shown thestrips extending vertieslly; but it is evident tiret the strips may helneed in various positions and ooou y various relations to each otherwithout esrting from the spirit of my invention.

hese strips, which are preferably east integral with the bars, ereprovided with a series of o enings E and E.

IiPdesired, supplemental holes or openings E' ofthe same or differentsize es E, me be provided. ln the drawings l have lustrsted the openingsF es being smaller than the openings E E ;'but l do not so limit myselfto this precise construction. The'bers G, in eonneetion with the beekplete l.) forni e series of pockets Gr, which are iilled with activematerial or material to beooine estive.

The openings E. E, and F serve the double purpose of keying the activemateriel ieee and also of allowing the eieetrigtie uid to more readilyreach the rear ends of the pockets G.

IDO

The openin F are ordinary perforations or holes; but t e openings E areso formed as to represent in longitudinal cross-section the form of atriangle. These openings 'are so formed as to extend into the rea'rportion of the bars C, and the lower sides of these conical openingsform the bottoms H loi" lflaring grooves that extend rearwardly throu hthe upper and lower faces of the bars C. n the lo case of the openings Ethe up er.sides of these conical openin grooves in the lower acesof thebars C. The

openings E E are shown in the drawings as,

circular; but it is evident that a square or x 5 other-shaped openingcould also be made,

which would at the same time form a similar rearwardly-laring groove inthe bar C.

In Fig. 4 I have shown ortions of opposite sides of the molds I J? fromwhich my zo plate shown in Fig. 5 is made, showing at the same time across-section of the late from which the molds have been with rawn.thisfigure, E F represent the dpins that form the o enings E, E', and F,an the lug or ofi"- set forms the pocket G. The condition and shape ofthese ins and lugs may be changed to provide different forms of platesthat come within the spirit of my invention.

I claim- 1. A battery-plate comprising end bars, a series of longitudinebars provided with a series of rearwardly-Haring grooves, and a seriesof strips extending across the op osite faces of the plate, and 1nstaggered re ation to each other.

serve to orm flaring seriesof rearwardly-Baring 2. A battery-platecomprising end bars, a series of longitudinal bars, a series of stri iextending acro the faces of the plate, t. i strips on the o posite sidesbeing in staggered relation to Yeac other and a series of kots formedbetween said bars, the strips orming the bottoms of the pockets.

3. A battery-plate comprising end bars, a series of longitudinal bars, aseries of perforated strips extendi across the faces of the plate, thestrips on t e op site sides being 1n st eredrelation to eac other, and aseries o fpockets formed between said bars, the strips orming thebottoms of the pockets,

4. A battery-plate comprising end bars, s series of longitudinal barsprovided with a oves, a series of strips extending across t e faces ofthe plate, the strips on the opposite sides being in staggered relationto each other, and a series 55 of pockets Yformed between said bars, thestrips forming the bottoms of the pockets.

5. A battery-plate comprising end bars, a series of longitudinal barsprovided with a series of rearwardly-Haring ooves, a 'series ofperforated strips exten ing Iacross the faces of the plate, the stripson the opposite sides being in st gered relation to each other, and aseries o pockets formed between said bars, the strips forming thebottoms of 65 the pockets.
